| Abstract | The Chance Constrained Linear Programming (CCLP) models have been
reviewed and extended for t he design (sizing) a nd operation of a multipurpose
water resources system. The multipurpose uses of the reservoir have been taken
as energy generation, flood control, irrigation water supply and low flow
augmentation. Hydro energy generation has been successfully incorporated in
the three forms of the linear decision rule (LDR). A 'predictive' rule which
includes t h e explicit consideration of correlation structure of flows h as been
compared with an 'independent' rule (which assumes uncorrelated flows) and a
'utopian' rule (which assumes a perfect forecast of the incoming flows). Comparison
or the different rules and forms of the models has shown the importance of the
accurate prediction of the highly stochastic streamflow.
The objective function of the models h as been taken as maximization of
energy generation with other constraints expressed as chance constraints with
explicit reliability criteria . The maximization of energy has also been done in
two forms - - maximization of total (annual) expected energy generation a nd t he
minimum expected monthly energy generation. A model without the use of a
linear rule has also been developed which maximizes the firm energy (90%
dependable energy) directly.
The models developed have been applied t o the case of a proposed Karnali
Multipurpose Project in Nepal and have generated guidelines that provide a
distinct tradeoff . between the capacity (size ), supply a nd t he reliability levels
achieved while arriving at the optimal development plan. The importance of a
well defined optimum operating policy and its influence in the final design of
the projects have a ls o been demonstrated. |
